Layered Charm describes this as a meditation ring. They say,”The inner bands rotate in a continuous spinning motion, which is thought to ease tension, soothe the mind and bring balance to the body.” I can see this also being a bit of a fidget spinner type of thing, where you may not be meditating, but you do get pleasure out of playing with the ring.

This is made of sterling silver, brass and copper and sells for USD$90.
